我有一個警報管理器在某個日期和時間顯示通知。 我安排通知如下：通知的警報管理器不起作用
private void scheduleNotification(String title, String text, String subtext, long futureInMillis) {
Intent notificationIntent = new Intent(getActivity(), NotificationPublisher.class);
notificationIntent.putExtra("title", title);
notificationIntent.putExtra("text", text);
notificationIntent.putExtra("subtext", text);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity(), 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getActivity().getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, futureInMillis, pendingIntent);
}
的廣播接收器：
public class NotificationPublisher extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Log.v("receiver", "notification received");
String title = intent.getStringExtra("title");
String text = intent.getStringExtra("text");
String subtext = intent.getStringExtra("subtext");
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
Uri uri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
builder.setSmallIcon(R.drawable.checkbox_on_24dp);
builder.setContentTitle(title);
builder.setContentText(text);
builder.setSubText(subtext);
builder.setSound(uri);
builder.setVibrate(new long[]{1000});
Notification not = builder.build();
NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, not);
}
}

我打電話安排通知如下：
int year = Integer.parseInt(date.substring(0,4));
int month = Integer.parseInt(date.substring(4,6))-1;
int day = Integer.parseInt(date.substring(6,8));
int hour = Integer.parseInt(time.substring(0,2));
int minute = Integer.parseInt(time.substring(2));
Calendar cal=Calendar.getInstance();
cal.set(Calendar.MONTH,month);
cal.set(Calendar.YEAR,year);
cal.set(Calendar.DAY_OF_MONTH,day);
cal.set(Calendar.HOUR_OF_DAY,hour);
cal.set(Calendar.MINUTE,minute);
cal.set(Calendar.SECOND,0);
String subcontent = catName + " due on: " + year + "/" + month+1 + "/" + day + " " + hour + ":" + minute;
scheduleNotification("To do!", shoppingListName, subcontent, cal.getTimeInMillis());
當我安排通知它似乎工作，但接收器從來沒有收到任何東西。
我到處尋找答案，我無法弄清楚爲什麼警報管理器不起作用。
